To all whom it may concern: 1

Be it known that I, WILLIAM J. LUTTON, a citizen of the United States,and resident? of Paterson, in the county of Passaic and State of NewJersey, have invented a new. and useful Improvement in Protector Mech-janism for Looms, of which the following is a specification. .7 i y .Myinvention relates to looms and more particularly to means for'throwingthe loom out of actionwhen the shuttlefails to seat properly inits box. f Y

My present invention is notintended to' supplant the bang-01f mechanismas usually, employed but is intended to act in conjunction therewith tomore eifectually prevent annoyance and damage from the breaking ofthreads, and particularly to prevent thelo'omfrom action untiltheshuttle 'hasjseateditself in'the box in'such position as toreceive theproper impact from the picker to carry it completely across the shed. JJ

In the accompanying drawings, Figure 1 is a view in end elevation of somuch of a. loom as will serve to illustrate my present invention, Fig. 2is a section through .the lay beam midway of one ofthe shuttleiboxes,

showing in elevation the parts immediately connected therewith,'Fig. 3is an enlarged view in end elevation of a part of the loom. frame andlay beam. showing the parts in the position which they assume when theshuttle fails to seat and the 100m is to be stopped, Fig. 4 is a view ofthe "controlling leverand parts connected therewith in the position oneof the loom boxesshowing in elevation the parts connected with thesub-swell for stopping the loom orpermitting it to act,

assume when the shuttle is fully seated within the box, Fig: 6 is' aviewin detail of the foot treadle for setting the trip lever, showingthe parts in the position which they i assume when the controlling leveris tripped, Fig. 7 isa similar view showingthe parts in the'positionwhich they assume when the controlling lever is setto permit the loom toact, Fig. 8 is a top plan view of the shuttle boxes and parts connected"therewith, the

same being shown on an-"enlarged scale and the loom. intermediate oftheboxes being broken away, Fig. 9 is a horizontalsection through oneof-the loom boxes, showing, the

Fig. 8 looking toward the inner face of the The loom frame is denoted by1; the lay beam'by 2; the pitmen for operating the lay is a view inelevation of the parts shown in beamby 3 and 4; the drive shaft by 5;the

brake wheel on the drive shaft by 6; the band brake by 7; the rockingarm for controlling the band brake by 8; the spring for actuatingthesaid arm by 9; the rod connected. with the rockingarm 8' and leading tothe rocking lever by 10; the rocking lever by 11; the controlling leverfulcrumed in axial alinement with the rocking lever 11 by 12 ,and thetrip mechanism forthe bang- Off by 13.

' r The dagger for operating the trip mechanism is denoted by 14; thearm of the toggle. lever for operatingthejdagger by 15 and 16; and therocking arm subject to pressure from the binder in the shuttle box by17.

The spring for operating the arm which leads to the foot of thecontrolling lever is denoted by 1 8; the arm itself by 19 and the foot;of the controlling lever with its diagonal slot by 20.

The foot lever for setting the trip and releasing the brake is denotedby 21 and its rod leading upwardly therefrom to the arm on the rockshaft is denoted by 22; the crank arm with which it is connected at itsupper end by23 and the shaft which is rocked by it to operate the tripby 24:.

The several parts above referred to are well known in the art andoperate in the present instance as usual.

Referring to the parts shown on a larger shuttle box is provided with abinder 25 which-worksthrough a slot 26 in the side of the box and ispivoted near one end as at 27 to swing intothe path of the shuttle whenthe shuttle is not in the box.

The shuttle is denoted by 28. As it is shown in Fig. 9, it has partiallyentered the box and is crowding the binder 25 back out of its path. r

The binder 25 is pressed toward the interior of the box by the'action ofa spring 29 fixed at one end to its outer face, its free end beingpressed upon by the arm 17 which operates the toggle lever l5, 16. Thebinder 25 is cutaway as at 30 throughout a considerable extentfrom itspivoted end toward i its free end preferably to a depth of about isprovided what I am pleased to call a subswell 31. This is convenientlypivoted on the same pivot 27 on which the binder 25 is pivoted but isfree to swing in and out independently of the binder 25.

The sub swell 31 is located in such position that it will not beoperated by the shuttle 28 until the shuttle has reached the limit ofits movement toward the end of the box in position to be struck by thepicker 32 a full blow to insure its travel across the shed.

WVhen the shuttle is in the position shown in Figs. 8 and 9 thesub-swell is in its inwardly rocked position and when in this position,a position which it assumes under the pressure of the spring 33, thebrake band will be held on the brake and the loom preventedfromoperating. This will be caused by the inward rocking position of an arm34 on a rock shaft 35, the free end of the said arm 34 being providedwith an adjustable bearing screw 36 which bears against the free end ofthe sub-swell 31 and determines the tension which the spring 33 shallhave upon the sub-swell.

The rock shaft 35 has fixed thereon crank arm 37, the wrist pin on whichengages an elongated open slot 38 in a crank arm 39 on a rock shaft 40,the said shaft being provided with a bifurcated clamping arm 41 betweenthe branches of which a dagger rod 42 is held by means of a screw 43 insuch position, see Fig. 3, that when the shuttle is in the positionshown in Fig. 9, and the sub-swell 31 rocked inwardly, the dagger rod 42will be in position to engage a tail piece 44 on the trip mechanism ofthe bangoff and will operate the bang-oil by setting free the rockinglever 11 and through the brake rod 10 will rock the arm 8 to set thebrake on the brake wheel. On the other hand, when the shuttle 28 entersits box, the full intended limit of its travel into position to receivethe full impact of the picker 32, it will crowd the sub-swell 31 backout of the interior of the box against the tension of the spring 33 andin so doing will rock the arm 34, the shaft 35, the crank arm 37, thearm 39 and the shaft 40' in such a direction that the dagger rod 42 willoccupy the position shown in Fig. 5, with its free end depressed out ofthe path of the tail piece 44 on the bang-01f mechanism and so the lever11 will not setthe brake on the brake wheel 6 and the loom will bepermitted to continue its operation.

By making the action of the binder independent of the action of thesub-swell, it becomes feasible to remove the pressure from the binderand hence leave the shuttle free to advance save only where it is heldnear its extreme end by the sub-swell thus giving it greater freedom ofmotion when once it is forced from the grip of the said sub-swell.

It will thus be seen that while the precautions which have heretoforebeen provided against the continued action of the 100111 when there isoccasion for arresting its action to prevent damage, have been leftintact, I have provided an additional guard against annoyance from theshuttle when it fails to receive the full impact from the picker and asa consequence fails to entirely cross the shed, by requiring the shuttleto be seated at the extreme intended limit of its travel in the shuttlebox before the loom can be set in operation, and, by so doing, I insurethe complete throw of the shuttle because it must be seated where itwill receive the full impact before the operation of the loom continues.Furthermore, this additional precaution has been provided for by astructure which will admit of its being readily applied to looms alreadyin use as well as to those which may be subsequently built.

lVhat I claim is 1. In a loom, the combination with a shuttle, a shuttlebox, means for operating the shuttle and means for arresting the actionof the loom, of a plurality of shuttle binders located in a shuttle box,one of said binders being at the extreme outer end of the shuttle pathand means connecting the said movable gripping device with the loomstopping mechanism whereby the action of the loom is arrested when theshuttle fails to reach the limit of its travel in the box.

2. In a loom, the combination with a shuttle, a shuttle box, means foroperating the shuttle and means for arresting the action of the loom, ofa binder movable into and out of the path of the shuttle as it entersthe box and a second hinder or sub-swell movable independent of theaforesaid binder and out of position within the shuttle box to engagethe shuttle as it approaches the limit of its throw and means connectingthe said sub swell with the loom arresting mechanism for preventing theaction of the loom when the shuttle fails to seat.

3. I11 a loom, the combination with a shuttle, a shuttle box, means foroperating the shuttle, means for arresting the action of the loom, of abinder pivotally secured in the shuttle box for gripping the shuttle asit enters the box, a sub-swell or hinder independent of the aforesaidbinder for gripping the end of the shuttle when it reaches the extremelimit of its travel and means for connecting the sub-swell or binderwith the loom stopping mechanism for arresting the action of the loomwhen the shuttle fails to reach the intended limit of its throw.

4. In a loom, the combination with a shuttle box, a shuttle, a binderpivotally secured in the side thereof and a spring for actuating thebinder, of a sub-swell pivotally secured to the shuttle box in proximityto the binder and free to swing independently thereof, a spring foroperating the sub-swell and a stop mechanism under the control of thesub-swell.

5. In a loom, the combination with'a shut tle box, a shuttle, a binderpivotally' secured therein and recessed throughout a portion of itslength, of a sub-swell pivotally secured in said recessed portion of thebinder, springs for operatlng the binder and subswell and a stop motionunder the'control of the sub-swell. A p r 6. In a loom, the combinationwith a shuttle box, a shuttle, a binder movable into and out of the pathof the shuttle and a sub-swell movable into and out of the pathof theshuttle, of a rock shaft under the control ofthe sub-swell, a daggercarried by therock shaft and a stop motion underthe control of thedagger.

. 7; In a loom, the combination with a shuttle, a shuttle box, means foroperating the shuttle and means for arresting the action of the loom, ofa plurality of shuttle retarding devices arranged to enter the shuttlebox intothe path of the shuttle and means for connecting one of theseshuttle retaining devices with the stop mechanism of the loomindependent of another.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two witnesses, this 27th day of July, 1906.
